- Any temperature of 38.0°C or higher in an infant under 3 months of age.
- Labored breathing, grunting, or chest retractions.
- Extreme lethargy, unresponsiveness, or inconsolable high-pitched crying.
- Dark purple or red non-blanching rash (petechiae).
❓ Frequently Asked Questions & Expert Answers
Can I use rubbing alcohol or cold water baths to lower fever?
Strictly dangerous! Cold baths cause shivering which raises core temperatures, while alcohol is rapidly absorbed through infant skin, causing alcohol toxicity and coma.
